At body temperature (37°C), the rate constant of an enzyme-catalyzed decomposition is 2.0 × 1011 times that of the uncatalyzed reaction. If the frequency factor, A, is the same for both processes, by how much does the enzyme lower the Ea?
67.1 kJ/mol
79 kJ/mol
662 kJ/mol
99 kJ/mol
8.00 kJ/mol
Uncatalyzed reaction has more activation energy than the catalyst reaction.
Answer is 67.1 kJ/mol
